This Gram-stained specimen reveals N. gonorrhoeae intracellular diplococci, leading to a positive diagnosis of gonorrhea.
The genus Neisseria consists of aerobic, non-spore-forming Gram-negative coccobacilli, which inhabit the mucous membranes of humans. These microbes require a moist environ... Read More
Magnified 1125X, this Gomori-stained photomicrograph revealed the presence of a Penicillium marneffei yeast cell, which was found in a specimen of human spleen.
P. marneffei is endemic to Southeast Asia, where it is one of the more common HIV-related opportunistic infections. Penicillium spp.... Read More

Magnified 1000X, this Liefson’s flagella stained photomicrograph revealed the presence of a number of flagellated Brevundimonas diminuta, formerly known as Pseudomonas diminuta.
After having run DNA-rRNA hybridization studies, the genus Brevundimonas has been reclassified as a member of the p... Read More
This photograph depicts the colonial morphology displayed by Gram-negative Haemophilus influenzae bacteria, which was grown on a medium of chocolate agar, for a 24 hour time period, at a temperature of 37°C.
Invasive disease caused by Haemophilus influenza type-b can affect many organ systems... Read More
At this point, after finding microorganisms that don’t mind extreme temperatures, pressure, aridity and other hardships, we shouldn’t be surprised that bacteria’s dominion over the Earth extends to just about anywhere we look. A new expedition to the Earth’s crust has reached unprecedented depth... Read More

Möbius strips are special loops that only have one continuous side. Now we've built the smallest Möbius strips ever - out of DNA. Here you can see the nanometer-sized DNA loops, folded like origami.
The ability to create complex structures on the tiniest of scales is one of the great challeng... Read More
